An improved DV-Hop Algorithm for Wireless Sensor Networks

摘要

The localization algorithm is an important issue for application of wireless sensor networks.As one of the range-free localization algorithms,DV-Hop algorithm can be simply implemented in real wireless sensor networks.In this paper,we propose an improved DV-Hop algorithm.This algorithm is derived from DV-Hop algorithm,and uses weight of anchors to improve localization accuracy without needing an additional hardware device.Simulation results show that the improved DV-Hop algorithm can provide more accurate location estimation than the DV-Hop algorithm.
